An Optometrist’s Malpractice Claim: A Missed Diagnosis and Its Fallout

A real optometrist's missed-diagnosis claim shows why diagnostic exposure matters—and why your employer's policy may not protect you.

You Diagnosed Correctly, But the Claim Still Came

You're an optometrist. You see a patient, run the tests, write the prescription. Everything looks normal. Two weeks later, a lawyer's letter arrives: the patient claims you missed early-stage glaucoma. You recheck your notes—you documented everything. But the patient says they're now losing peripheral vision, and it's your fault.

That scenario isn't hypothetical. According to a real case reported by Berxi, an optometrist faced a claim after a routine eye exam—not for a missed diagnosis, but for an alleged injury from the chin rest. The patient claimed the chin rest knocked out a tooth. The optometrist remembered no such incident, and the claim ultimately didn't hold up. But the stress, the time, the fear—that was real.

Diagnostic errors are one of the most common reasons optometrists get sued. Missed glaucoma, delayed retinal detachment diagnosis, failure to spot a brain tumor during a routine exam—these cases happen more often than you'd think. And the fallout isn't just emotional. The National Practitioner Data Bank reports that 26% of all medical malpractice payments from 2012 to 2022 involved non-physicians—including optometrists.

So, what happens when a claim comes? And is your employer's policy enough?

What a Missed Diagnosis Looks Like in Real Life

Let's walk through a typical scenario, based on anonymized claims data.

A 55-year-old patient comes in for a comprehensive exam. You check intraocular pressure, examine the optic nerve, run a visual field test. Everything is within normal limits. You prescribe reading glasses and send them on their way.

Eight months later, the patient goes to another optometrist complaining of blurry vision. That doctor diagnoses advanced glaucoma with significant field loss. The patient sues you, claiming you should have caught it earlier. Their attorney argues that standard of care required additional testing—maybe an OCT scan—or a shorter follow-up interval given the patient's age and family history.

Your defense: You followed standard protocols. The optic nerve looked healthy. Pressures were normal. But now you're spending hours gathering records, talking to your insurer, and worrying about your reputation. Even if you win, the process is brutal.

That's exactly what the Berxi optometrist experienced. Her claim was eventually dismissed, but she told the claims team that the anxiety affected her work and sleep for weeks. As Berxi's claims examiner Ed noted, “Even when a claim seems baseless, the emotional impact is very real.”

Does Your Employer's Policy Cover Diagnostic Errors?

Maybe. But probably not in the way you need.

Most employer-provided malpractice insurance is claims-made. That means it only covers claims filed while the policy is active. If you leave that job—or if your employer changes carriers—you lose coverage for past incidents unless you buy tail coverage (extended reporting endorsement), which can cost 1.5 to 2 times your annual premium.

Even more important: Employer policies are designed to protect the facility first. They often:

Diagnostic errors, by nature, often take months or years to surface. A glaucoma missed today might be discovered two years from now—when you're working at a different practice. Without your own policy, you'd be uninsured for that claim.

What Your Own Policy Should Include

If you're an optometrist—whether you own a practice or work as an employee—you need individual coverage that addresses diagnostic exposure. Here's what to look for:

If you choose a claims-made policy (like some from Proliability or CM&F Group), make sure tail coverage is available and budget for it.

How Much Does Optometrist Malpractice Insurance Cost?

Premiums vary by state, claims history, and coverage limits. For optometrists, annual premiums typically range from about $500 to $1,500 for $1 million per occurrence / $3 million aggregate. A policy with higher limits or occurrence form will be at the upper end. Final pricing comes from the carrier at quote, so always get multiple quotes.

The Lesson from That Chin Rest Claim

The Berxi optometrist's claim was unusual—a patient alleging a dental injury from equipment. But the lesson applies to any diagnostic claim: you can do everything right and still get sued. What saved her was having a responsive claims team and a policy that covered the defense, even for a seemingly frivolous allegation.

If you're an optometrist working for someone else, don't assume you're covered. Ask your employer for a copy of the policy. Check if it includes license defense, tail coverage, and your name as an additional insured. If it doesn't, buy your own. It's not about distrusting your employer—it's about protecting your career.

Frequently Asked Questions

Can an optometrist be sued for a missed diagnosis? +

Yes. Missed glaucoma, delayed retinal detachment diagnosis, and failure to detect systemic conditions like brain tumors are common claims. Even if you followed standard protocols, a patient can sue, and you'll need legal defense.

Does professional liability cover diagnostic errors? +

Yes, professional liability insurance covers claims of negligence, including diagnostic errors. Policies typically cover legal defense and settlements or judgments up to your limit. Occurrence forms cover incidents that happened during the policy period, regardless of when the claim is filed.

Do solo practitioners need their own policy? +

Absolutely. Solo practitioners have no employer policy to fall back on. You need individual coverage that includes license defense, consent to settle, and portability. Even if you're an employee, your employer's policy may not protect you adequately.
